问题描述
我最近使用 react-native init 构建了新的应用程序.
I recently build fresh app using react-native init.
运行 react-native run-android 后，我收到此错误:
After run react-native run-android I got this error:
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':app:preDexDebug'.
> com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:\Program Files\Java\jdk1.8.0_112\bin\java.exe'' finished with non-zero exit value 1

Could not install the app on the device, read the error above for details.
Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:

我已经尝试在我的 android 文件夹中运行 gradlew clean 但仍然没有运气.
I've already tried to run gradlew clean inside my android folder but still no luck.
有什么解决办法吗?
推荐答案
遇到了同样的问题，经过大量故障排除后我发现 android 项目已损坏.这是我修复我的方法:
Had the same issue, and after a lot of troubleshooting I found out that the android project was corrupted. Here's how I fixed mine:
来自项目文件夹:
rm -rf androidreact-native 升级
注意:只运行 react-native upgrade 而不删除 android 文件夹似乎不起作用.
Note: just running react-native upgrade without deleting the android folder does not seem to work.
